Nude handstand

From The Original Sex Wiki

Nude handstand is a naked sport at Voyeurcloud and a special type of nude workout: She balances on her hands trying to balance her body in a complete stable vertical position - of course while being completely nude.
The nude handstand serves several purposes:

Blood flow to her brains is being increased

Her toes can catch some fresh air up there.

The forces on her tits are being inverted sometimes leading to interesting effects depending on the weight of her boobs.
